the structures that, with the conjunctival sac, produce and provide drainage for lacrimal fluid (tears), consisting of the lacrimal gland, the lacrimal lake, the lacrimal canaliculi, the lacrimal sac, and the nasolacrimal duct.
A diffuser airflow rate is 50 cfm per linear foot (77.4 L/s per linear meter) of diffuser. Therefore, the recommended flow to use when designing is 50 cfm/ linear ft x 0.8 = 40 cfm/linear ft (77.4 L/s/ linear m x 0.8 = 61.9 L/s/linear m). The nominal airflow of a diffuser is determined by multiplying the diffuser length, the number of slots, and the airflow per linear foot. Using the airflow per linear foot calculated above, a 4 foot, 2-slot, 2-way diffuser should be designed to handle 4 linear ft x 2 slots x 40 cfm/linear ft = 320 cfm (1.219 m x 2 slots x 61.9 L/s/linear m = 150.9 L/s). To maximize the effectiveness of ventilation with ceiling diffusers, throws should be kept as long as possible.
First unit: Million standard cubic feet of gas per day (MMSCFD at 15Â°C) is used for measuring gas flow. Second: cubic meter per hour (m3/h) is unit of flow rate. Million standard cubic feet per day (Redirected from MMSCMD) Million standard cubic feet per day is a unit of measurement for gases that is predominantly used in the...
